Method Summary

void

onGuardableRecovery(Guardable guardable, Service service)
Take appropriate action after the specified guardable (associated with the specified service) has missed a "soft-timeout" and has entered the "RECOVERY" state.

void

onGuardableTerminate(Guardable guardable, Service service)
Take appropriate action after the specified guardable (associated with the specified service) has missed a "hard-timeout" and has entered the "TERMINATING" state.

onServiceFailed

Take appropriate action after some service failed to stop. The failed service may be hung, deadlocked, or otherwise in an inconsistent and/or unresponsive state.

This method will be invoked on a dedicated thread; further failures, hangs, or deadlocks of failure handling logic will not directly affect other healthy service threads.

Note: it is strongly advised that, at a minimum, any failure policy should attempt to stop the cluster services (e.g. via Cluster.stop()) or otherwise ensure that they are stopped, in order to isolate any failure from the rest of the cluster.
